Application filed January 31, 1920. Serial No. 355,452.

To (17/ 111/: um it may concern:

Be it known that we. Lorns A. Oscoon and ELMER E. VVoLr. both citizens of the United States, Osooon residing at Dayton,

Montgomery County State of Ohio, and

WoLr residing at Springfield, (larlr County. State of Ohio, have invented certain new and useful Improvements in Counting Devices for Scales, of which the following In is a full. clear and exact description.

The object of the present invention is to provide an apparatus for the attachment to a scale to provide means for counting the number of articles upon the scale platform or for determining accurately when a de sired number'of articles of substantially uniform weight have been placed upon the platform.

Like other counting scales the device cm bodies a receiver in which a definite number of articles maybe placed to form a counterbalance weight. Means are provided for adjusting the'position of the receiver upon the beam to any desired position and for simultaneously moving a poise on the beam to counterbalance the weight of the rcceiver, whereby the weight of the articles in the receiver alone reacts against the beam.

The present invention resides in the improvement of construction oi counting scales of the type embodying a shittahle weigh receiver and poise in which rack and pinions are used for effecting the displacement of the parts. These scales may be provided with indicating devices in the Form of dials having multiple graduated scales and provided with cooperating pointer. One of the objects of the present invention is particularly directed to means for settingthe pointer to sweep over the desired scale and injthe association with such means of an index device which designates the number of articles to be placed in the 4- receiver for a particular setting of the in dew: and for a corresponding position of the pointer.

In th s type of counting scales such means as racks and pinion are provided for manum all setting the position of the receiver which obviates the use of cords and pulleys or right and left hand screws. In the presout embodiment. use is made of this setting device. The present embodiment also ntilizes the multiple dial and cooperating pointer to determine the count as shown in the application referred to above.

- Another object resides in the provision at a supplementary dial which is arranged to show a number corresponding to thetotal count represented by one revolution of the pointer, and this count number is progressively increased each time the pointer is turned through one complete revolution. The index device and supplemental dial are so arranged that the proper. count will be displayed by the supplementary dial at each revolution of the'point er', regardlessof the setting of the index and the position of the pointer. I 1 P: l

The total count is'displayed at the dial by the turning of a single knob and the use of doubling or slip-on'fw'eights is obviated, thereby minimizing the possibility of error which is attendant upon the mental calcu lation necessary {when they aroused. i

Other objects reside in certain details of. construction which will hereafter be set forth in further detail. i i I In the drawings, I

'llie,.-i'1ule is pr0- rideil with a spring plunger 35 ii'urming a lQtRlXlll." device :ulupted tu ruopernt .with holes in the turned over periphery of dial 26 (see Fig: (3). By pulling outwardly. upon plunger 35 and shifting the same eirruniferentially, theindexS-l can be aligned with the figures IUO. 5U 20 or 10, on the periphery of. fixed (llill 26. These numbers designate the particular number of articles-t0 he plueerl in the receiver for. Hurt-setting 0f the index. When the index 3%,is mere-(l to its \Lll'lfillS positions, the pointer 81 is 1110\Qal i ll vii -li automatically by the movement of the index so that its end is adapted to sweep over the particular scale corresponding to the selected index position and the number of 6 articles in the receiver. To effect this setting of the pointer we provide a link 36 having one end loosely mounted upon a pin carried by fixed disc 26 (see Fig. 4). The opposite end of link 36 is connected by a pin connection-to a semnd' link 37: which at its 'opposite-end is bowed and provided with a suitable stud which secures a shoe 39 thereto. Iritermediate the ends, link '37 has a pin connection with a link 38 which at its lower end has a pin connection to shutter 33.

By the movement of index 34, linkage 36, 37; '38 causes'shoe 39 to slide vertically in a vertical slot 40 in a member 41 which is fastened to stud 16 (see Figs. 4 5, 6). Upon the outerface of member 41 are a number "o*f' conc'entric circularslots or grooves 42, 43 =44' and' l5,- and these slots are at such positionms toalign with the'center of the shoe 'when'thei index is moved to different nuhiber"positions'. With index at 100 the W shoewil l 'befopposite slot 42. at 50'uosition t'lresfhoewill'be oppositc slot 43, at 20 position theshoe will be opposite slot 44, and atfLO 7 o sition the shoe will be opposite slot 45'. I hefinner face"(i. e, towards member 40) i's-grooved withzit-circumferential groove which i's 's imilar in size to grooves '42, 43, 44 an'dfl lfil With'inthis'grooved part of the shoe-is ines which pin is fastened to a -f' sh'ort link 47 vvhiclris rigidly fastened to pointer'3l flseeFi s. 5and 6). The mover'nehtofthe shoe up and down will impart a corrcsponding moveuicnt of'the pointer 31 through the pin 46 and link 47. In this way 39 the pointeris brought in sweep over a pa rticula'rlyscale 27, 28. 29 or 30, correspond ing with index positions 10, 20, and 100v After the pointer has been adjusted it may be freelyrotated b r turning the knob 17 5 5 In this rotationthe pin 46 moves in the particular slot 42, 43, 44 01145 opposite which it has'-previously"been positioned. After once setting the index 34 and turning knob 17 the pointer cannot be brought to a dif- 5( 1 ferent scale position until the parts are restored to normal position. In order to counterbalance-the pointer we provide rack teeth on the side of the pointer which teeth mesh w'ith and rotate a small pinion 48 which is freely rotatable on shaft 17. Pinion 48 meshes with a rack 49 which is guided for a sliding vertical movement in member 32 so that as the pointer 31 moves outwardl" racl;"'-'49 "moves outwardly or vice verse to f thereby I effect 'a counterbalance of the pointerirresp'ective of its position.

' In'order on the dial the count when knob 17 is turned through more than one revolution.

6 we provide means for indicating the gross to provide means for indicating count figures corresponding lo one or more revolutions adjacent the zero point of the scales on dial 26. The construction is such that the showing of the supplemental amount or gross figures appears imn'iediatelv after the pointer.31 passes the zero position.

It is not desirable to have these figures'appear gradually ass-there is a possibility of error'in the reading when they so appear. Furthermore the means provides fore-the progressive appearance of gross count figures representing the gross. units adjacent all-four of the scales on dial'26.

Referring to Figs. 2 and 4; fixed dial 26 has four Windows 50,51,5253, directly tothe 305 left of the zero point of scales 27, 28. 29 and 30, and below'the graduation? as shown in Fig. Shutter 33 has likewise four win dows 54, 55, 56157;:which are staggered with respect to each other.- The loeationof'these' windowsis such that=withindex :in the =1O'l1 position as shown in Fig. 2 windows 50 and 54 will align and when the-index is moved to the 50, 20 and 10 positions, respectivelyj windows '55, '56 and 57 will progressively align with windows 51,252 and 58 andpermit a reading to be made of numbers on a supplementary dial :58. '-:;It will be under stood that with one setting-two windows only are aligned permitting'a single reading of the numerals upon! supplementary idiali 58'which corresponds'to the particularset ting of the index"'34.

Supplementary dial 58 carries four concentric rows of grosseount figures 79, 80, 81 and 82, representing the gross counts corresponding to the amount represented by one revolution of the pointer over scal'es27.

28, 29 and 30. -E'ach row of figures is made up of a series of progression 'of gross count figures corresponding to l, 2, 3. 4 and 5 revolutions of the pointer. Supplementary dia] 58 is-of sector shape and is fastened to a-disc 58 which is rotatably mounted upon stud 16 (see Fig. 6'). "Pivoted upon a stud 60 carried by disc 58' is a stepped tooth seg ment 6]. which has fastened thereto a tension spring 62 suitably fastened at its opposite end to a fixed part of the device or if desired to shutter 33. The stepped tooth segment 61 11s is prevented from swinging inwardly by a stop fil but can swing outwardly against the tension of the spring.

Fastened to the receiver poise is a. flat plate 63 which is likewise provided with a stepped edge. The distance between the steps corresponds to the distance poise 21 moves for one rotation of knob 17".

Stepped tooth segment 61 cooperates with the edge of plate 63 so that when the plate is moved a distance corresponding to one revolution of the knob the stepped segment will swing up under the influ nce of spring 62 and engage the first step with the first step on plate 63.

The rotation of the stepped segment causes the supplementary dial to more to a proper extent to display' the proper gross count through the previously aligned windows.

"Upon the return movement of the parts the stepped segment swings away from the stop (31 thereby Freeing the steps of the segment from the steps of plate 63 and permitting the return of the poise and other parts to 191' normal position.

It, is desirable to prevent the movement of the index after the knoblF-is partially turned and rlntil itis restored to normal position. "l his is accomplished by means of a sectorshapod plate 65 having notches 36 on the periphery. lhis plate 65 is fastened to thefshnttor, 33am upon move ment of the knob! I'l -the plate 63 projects iilto -the-notohes arid-thereafter prevents a mminient ofirth shutter by the index until thefparts arer'esfiordto normal position.
